SPECIFICATION forming pari: of Letters Patent No. 361,086, dated April 12, 1887.

i Application tiled January 26, 1887, Y Serial No. 225,555. (No model.)

.To all Awhom it may concern: N

Be it known that I, CHARLES SOHEIDL, a citizen of the United States, residing in Phoenixville, .Chester county, Pennsylvania, have invented an Improved Subway, of which the following is a specilication.

The object of my invention is to provide a subway which may be quickly and economically constructedl and yet be of great strength; and this object I attain by constructing the subway of a series of independent self-contained metallic frames arranged at intervals and connected or united by masonry or metallic walls, as hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a transverse section on the line 1 2, Fig. 3, of a subway constructed in accordance with my invention. Fig. 2 is alongitudinal section on the line 3 4, Fig. 1, of a portion of the same. Fig. 3 is a sectional plan view on the line 5 6, Fig. 1, also of a part of the subway; and Fig. 4 is a perspective view of one of the self-cou tained metallic frames usedin carrying out my invention.

My improved subway may be used for an underground street, or street or steam railways, and for the conveyance of water, gas, or steam, 0r pneumatic mains or pipes, or for electrical conductors, either in the form of individual Wires or cables.

. In the drawings I have shown a subway constructed for the accommodation of two railway-tracks or equivalent passage-ways, A A', and at one side a part, B, for the conveyance of electrical conductors and mains and pipes for water, gas, steam, or pneumatic purposes. I do not, however, wish to limit myself to this or any other particular arrangement of passage-ways in the conduit.

In the erection of my conduit I build a series of separate self-contained frames,substan' or more intermediate supporting-columns, E,

depending on the width and desired strength ofthe subway. In thepresent instance Ihave shown two such columns in each frame. The beams and columns may be of channel or angle iron,or any other desired or convenient shape vals apart-say five feet-on a suitable founda tion, f', of cement or other convenient material, as illustrated in Figs. 2 and 3. The frames thus arranged are connected at the sides and top by walls of masonry or iron-work to support the pressure of the earth and overhead traffic. In the present instance I have illustrated the side columns, G C, of adjacent beams as united by walls of masonry, brick arches F being built in between the upright beams, Figs. 1 and 3, (with a cement filling at the back,) to withstand the pressure of the earth. The top wall or roof is formed in the present instance of metal, a series of plates or bars, G, being laid longitudinally side by side along the tops of the crossbeams of the metallic frames and secured to the latter, Figs. 1 and 2.

On this roof is laid the cement or other founda` tion for the roadway above. Instead of this metallic form of roof, it may be constructed of masonry with brick arches connecting the metallic frames, as the above-described side walls are constructed, and as indicated by dottedy lines at the upper left-hand side of Fig. 2; and on the other hand the side walls may be formed of the channel-bars G, secured horizontally to theuprightendbeams. Ifdesired,brickarches, similar to the arches F, forming the side walls of the subway, may be employed in forming the bottom thereof, as indicated by dotted lines in Fig. 2. In such case the form of the beams D' would have to be changed, as also indicated by dotted lines in that gure.

'If desired, the frames may be further connected with each other by braces e, running from the columns E of one frame to the correspondiug columns of the adjacent frames. y In Fig. 2 I have shown the frames thus braced in sets of three. lThe parts of the frames which are in the part of the subway for the accommodation of the gas andwater pipes and mains, electrical conductors, 8vo., may be provided with suitable crosspieces,p p, for the support of the various mains, pipes, conductors, 85e.

The abovedescribed form of subway, it will be evident, can be much more quickly and economically constructed, and is much stronger IOO than one having independent columns and arches.

I claim as my invention- 1. A subway composed of a series of selfeontained frames or columns and beams, with side and top walls of masonry or metal eonnesting the several frames, substantially as set forth.

2. A subway composed of a series of selfcontained frames of columns and beams, with side walls of masonry and top wall or roof of metal uniting the frames, substantially as set forth.

3. The combination of frames composed of top and bottom beams and end and intermediate columns, with side and top walls of niasonry or metal connecting the several frames, the whole forming a subway, Substantially as described.

4. The combination of frames composed of zo top and bottom beams and end and intermediate columns, with side walls of masonry and top wall of metal bars uniting the several frames, all substantially as set forth.

In testimony whereof I have signed my name 2 5 to this specification in the presence of two subscribing witnesses.

CHARLES SCHEIDL.
